yup, im still working on transmitters :lol: . i perfected my 9v transmitter, but then found out the battery life is crap compared to a 3v transmitter . . . so, now im onto the good 3v transmitter . . . and ive got my questions.
I am doing nothing different from the schematic accept for using 2n3904's and using a 8pf cap instead of 5.6pf cap for C5. One thing that must be known is that i have the circuit assembled on a piece of cardboard with long leads.
1. It transmits beautifuly. The thing is, when i use the .022uf decoupling cap, the thing starts sounding like a fly over the radio. I tried using a 100uf cap to take this away, but it only added to the problem.
2. Are there any simple improvements that i could make on this circuit to improve range, etc.?
Thanx much :lol:
